Saving money, finding price information

cashkaro is a website offering cashbacks on different products purchased online
Despite unsubscribing repeatedly, the website Cashkaro continues to send spam emails daily to a google competitor , domain investor and obc bhandari engineer. Due to the google, tata masterminded sex racket, identity theft fraud, the domain investor, engineer and google competitor has very less money, and cannot afford to purchase many items online, and cannot use cashback websites like cashkaro because they do not offer a cashback on amazon
Yet Cashkaro continues to spam the domain investor daily in september 2017, allegedly the powerful associates of the google, tata sponsored goan gsb fraud cbi employee riddhi nayak, like caro, mandrekar, nayak are using this as part of their never ending mental harassment methods, that they want to take over the online business, and pay the the obc bhandari engineer cash
These spineless dishonest fraud goan gsb intelligence and security agency employees have not purchased any domain name or website till date, paying the market price, yet are sending emails daily from Cashkaro allegedly to create an atmosphere of fear, mental stress.
